The Application of Intelligent Monitoring System in Underground Excavation of Existing Subway Stations
[Purposes]In order to ensure the structural safety of the existing operating subway station dur-ing the construction of underground excavation,it is necessary to study the monitoring point layout and real-time monitoring technology of the underground excavation of the existing Zhongsheng station of line 10 by the newly built Zhongsheng station of line 7.[Methods]Different technical equipment is used to monitor the monitoring points laid out in the same structure and section,and the accuracy of monitoring data and the timeliness of data provision are compared.And then,this paper and analyzes the layout method of the settlement monitoring points at different positions of the overall structure of the station and the rapid data acquisition,transmission,storage and management capabilities of the real-time monitor-ing technology equipment of the intelligent monitoring system.[Findings]The results show that although the station is the overall structure,there are differences in the amount of settlement change at different positions.The intelligent monitoring system can better realize the integration of the data of the measuring robot and the static level,and can ensure the analysis and transmission of the real-time monitoring data of the underground excavation project.[Conclusions]The intelligent monitoring system can be applied to the monitoring of subway tunneling project,which can provide reference for future tunneling projects.
